Get value of select loaded with AJAX

I am loading a select via AJAX and then trying to use the value of the select for another AJAX call.

So I have: 

<select id ="thisSelect">
  <option value = "someValue1"> Some Value 1 </option>
  <option value = "someValue2"> Some Value 2 </option>
</select>

This loads fine. Then I am trying to access the value of thisSelect like so: 

$(document).ready(function(){
    var value = $('#thisSelect').val(); 
    alert(value); 
});

It only registers the first value that the select loaded with in the original AJAX call and isn't capturing any of the changes.

Any ideas? I tried: 

 $('#thisSelect').on('change', function() {
    var value = (this.value);
    //or
    alert(this.value);  
});

in the same $(document).ready block, but 'value' shows up as undefined and I don't get an alert box.

You could try 

var array = [];
var i = 0;
$("#thisSelect").children().each(function () { array [i++] = $(this).val; });

It'll throw the values into an array you could then access.

It sounds like your content is loaded after the on change statements are run.

Use a delegated event handler for the change instead:

 $(document).on('change', '#thisSelect', function() {
    var value = $(this).val();
    alert(value);  
});

This works by listening for the event to bubble up to a non-changing ancestor element (document is the default if nothing is closer). It then applies the jQuery selector at event time, so the item only has to match then.
